重叠

The formula of the overlap area and the overlap rate were derived from its definite integral form.

并利用积分方法，推导出了林木树冠发生重叠时的重叠面积和重叠率的计算公式。

The results are as follows:From the overlap degree of native plant species abundance hotspot, relative endemism hotspot and representative hotspot, East and West Sheshan. Dajinshan Island, Tianmashan, Dianshanhu are the geographic units of the three hotspot overlapping, Chongming Dongtan, the Fengxian Bay are two hotspots overlapping geographic units.

根据研究，本文得出以下结论：从植物丰富度热点、特有性热点、代表性热点的重叠程度来看，东、西佘山、大金山岛、天马山、淀山湖是三类热点重叠的地理单元，崇明东滩、奉贤海湾是两类热点重叠的地理单元。

Using the Shannon-Wiener's niche breadth index and the Pianka's niche overlaps index, we found that the Nereis japonica, nemerteans and eelworms had broad niche breadths (above 2.80); the niche overlaps among them was high (above 0.90) in the quantitative analysis on the 21 species present in the quantitative sample analysis.

对定量取样中获得的21个物种以Shannon-Wiener指数为基础进行了生态位宽度测定，以Pianka重叠指数为基础进行了生态位重叠值分析，结果表明日本沙蚕、纽虫和线虫的生态位较宽，均为2.80以上，它们之间的生态重叠值也较高，均为0.90以上。

In addition, the ICP algorithm provides the benefit of avoiding the need to interpolate the raw laser points, and evaluating the height as well as the planimetry offsets from overlapping laser strips. To evaluate the performance of the algorithm across different data quality level, two data sets are tested. The results reveal that the ICP algorithm can be used to both quantify the discrepancies from overlapping strips, and identify a solution regarding the correspondence problem.

使用两组经地面参考资料检验精度等级不同之扫描资料测试，结果显示，ICP不仅能作为重叠航带间之资料精度评估工具，同时也可以解决搜寻重叠航带间对应点之问题，而这个问题在评估重叠空载雷射航带间之精度及后续系统误差改正时，为非常重要的一项课题。

The sample comprised 25 patients with the first premolar removed during orthodontic treatment. Digital models and lateral cephalometric records were taken pre- and post- treatment. We chose two kinds of regional superimposition methods on the digital models (One was the mesial zone of the third primary ruga and regional palatal vault, the other was the palate) and Baumrind's best-fit for cephalometric superimposition. The amounts of incisor and molar movement were measured and a comparative study was performed.

三。选择25例拔除上颌第一双尖牙正畸患者治疗前、后的上颌模型进行三维重建，分别使用第三腭皱近心端局部腭穹隆和腭部对同一患者治疗前、后的数字化模型进行局域重叠，以治疗前后头颅侧位片的 best-fit重叠为评价标准，比较三种方法之间的差异，对应用三维数字化牙颌模型纵向重叠评价正畸治疗前、后的牙齿移动进行探索性研究。

To analyze 12 cases (male 10 and female 2) of double infected with typhoid fever and malaria over the past ten years in our hospital. Results: Of them, 8 cases suffered fioom typhoid fever with tertian malaria, 3 cases of typhoid fever with falciparum nalaria, anid the other one was diagnosed by anti-malaria treatment.

收集我院近十年来的伤寒、疟疾重叠感染患者12例(其中男10例，女2例)结果：12例伤寒重叠感染间日疟8例、恶性疟3例，疟原虫阴性的1例是在确诊伤寒后，按伤寒治疗，高热持续不退，贫血加重，经诊断性抗疟治疗，体温降至正常才诊断为重叠感染的。

There are large niche overlaps between the shrub and semi-shrub species and among the herbaceous plants of which the overlap between H. scoparium and A. ordosica and between Chloris virgata and Bassia dasyphylla were 0.7192 and 0.8622, respectively, and this indicates that they have greater ecological similarity thus possessing strong competitive capacities in community succession; there are smaller niche overlaps between A. ordosica and various herbaceous plants and thus they can stably co-existed.

灌木、半灌木种之间、草本植物与草本植物之间的生态位重叠值较大，其中花棒与油蒿、虎尾草与雾冰藜之间的生态位重叠值分别为0.7192和0.8622，这表明二者之间有较大的生态相似性，从而在演替过程中具有较强的竞争作用；而半灌木油蒿与各草本植物之间的生态位重叠值很小，它们能够实现稳定共存。

Shrubs and undershrubs in desert-oasis ecotone can be divided into four groups based on the niche breadth. Based on the niche overlaps matrix, overlap between Reaumuria soongorica and Haloxylon ammodendron is large; overlaps among Kalidium foliatum、 Suaeda physophora、Kalidium caspicum、Tamarix ramosissima、T. elongata are large; the others'overlaps are small.

阜康荒漠绿洲过渡带灌木、半灌木按生态位宽度可分成4类；根据生态位重叠矩阵，红砂和梭梭之间、囊果碱蓬、里海盐爪爪、多枝柽柳和长穗柽柳之间重叠较大，其余种重叠值均较小。

The larger the niche overlap of two species is, the more similarly resource space they occupy. the niche overlap of Leontopodium leontopodioides and Polygonum viviparum amounts to 0.892 (in the community Ⅰ). This proves that they are very similar in utilizing the resources. In the general community, the niche overlaps among species are very low.

两个种群的生态位重叠值越大，说明它们占据越相似的资源空间，珠芽蓼和火绒草的生态位重叠值高达0.892，说明它们利用资源的相似性程度很高；在总群落中，各种群之间生态位重叠值都很低。

This paper is about the research on the structures, meanings and ways of expressions of the geminating forms of monosyllabic adjectives in both Chinese and Vietnamese.

本文在汉语与越南语单音节形容词重叠式研究的基础上，根据笔者对越南语的亲身体会，运用汉语和越南语单音节形容词重叠式对比翻译的分析等方法对汉-越单音节形容词重叠式的结构形式、语法意义和表达方式进行研究。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
